CLARENCE E. JANES, OF NEW YORK, N. Y.

SASH-LOGK.

Application filed October 24, 1913.

To all whom it may concern Be it known that I, CLARENCE E. JANES, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Sash-Lock, of which the following is a full, clear, and exact description.

My invention relates to means for locking sliding window sashes, and particularly to a device of the indicated character comprising separate sash-locking means separately attachable to upper and lower sashes, and each having a bolt or equivalent element adapted to be projected to a position to engage the window frame, together with actuating means for the bolt, said actuating means including a coupling bar adapted to couple the two sash-locking means when the same are brought into alinement, whereby the coupling bar will form a connection between the two sashes, as a locking means therefor, in addition to the separate locking of the separate sashes to the window frame by means of the bolts.

The distinguishing features of the invention, and the important structural elements characterizing the practical embodiments which are illustrated as examples, will be more particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a face view of a portion of a window frame with the upper and lower sashes having my invention applied thereto; Fig. 2 is a horizontal section; Fig. 3 is a vertical section on the line 33 of Fig. 2; Fig. 1 is a vertical section on the line 44 of Fig. 2; and Fig. 5 is a view similar to D Fig. 2, but illustrating another form of the invention.

The lnventlon is illustrated 1n connection with upper and lower sliding sashes A. B,

Specification of Letters Patent.

Serial No. 797,024.

there is provided on each sash a sash-locking means designated generally by the numeral 10, and applied to the respective sashes at the meeting rails, thereof, so as to aline when the sashes are in the closed position. In addition, there may be one or more of such means along a side rail of either or both sashes, for use in looking either or both sashes partly raised or lowered. The sash-locking elements on each sash are illustrated as comprising a bolt casing 11, fitted in a suitable mortise in the sash and properly secured by suitable fastening devices 12. Each casing has a sash bolt 13 adapted to be projected laterally beyond the adjacent side edge of the sash into engagement with a suitable element on the window frame, as for instance, into a socket 1 1.

As constituting one actuating means whereby the bolts may be projected or retracted, I have shown said bolts as formed with racks 15, meshing with which are pinions 16, said pinions being formed to receive and be turned by a bar 17 which ranges at a normal angle to the bolts, and is provided with a knurled head 18 or equivalent means for the convenient manipulation of said bar.

The bar 17 is adapted to be moved lengthwise to insert or withdraw the same, there being provided in the sashes and in the bolt casings, keyhole openings 19. The keyhole form of the openings provides for accommodating lateral studs 20 on the bar 17, said studs being so positioned that when the bar is entered in the sashes and lock casings, the studs 20 will be within the lock casings and be accommodated in recesses 21 in the pinions 16. A turning of the bar 17 on its axis in a proper direction will, through the medium of the pinions and the racks 15, project or withdraw the bolts 13. In the projected position the studs 20 will be out of register with the keyhole openings 19, and the bar will thus be locked against withdrawal or axial movement until the bar is deliberately turned to bring the studs 20 into proper position relatively to the keyhole openings.

The studs 20 by projecting laterally into the recesses 21 of the pinions, serve incidentally to engage and turn the pinions when the bar is turned, and thus actuate the bolts, but I prefer to form the bar 17 polygonal,

or otherwise non-circular in cross section,

and to form a corresponding eye or bore in the respective pinions 16, as clearly illustrated in Fig. 4, whereby the pinions will be turned with the bar when the latter is in position. To hold the parts in position with the bolts projected, I have shown a spring pawl 22, secured at one end to the interior of one casing 11, and provided with an upwardly projecting finger-piece 23.

With the described construction, the two bolt-casings on the meeting rail will be so positioned when the sashes are closed as to aline the keyhole openings 19 of the respective sashes to permit the bolt 13 to be moved longitudinally into an engagement with bolt pinions 16 and both bolt casings 11, in which position the bar constitutes a coupling bar not only between the two lock casings, but between the two sashes, since it extends continuously therebetween. Thus when the bolts are projected into engagement with the window frame, the sashes will be separately locked to the frame by the bolts, and in addition the bar constitutes a coupling be tween the two sashes and a connecting means between the two locking means. For an intruder to surreptitiously open either sash it will be necessary for the coupling bar 17 to be sawed between the sashes, and in addition, the bolt of either sash would need to be retracted.

In the form shown in Fig. 5, a bolt casing 11 is secured to each sash as by suitable fastening devices 12 and provided with I sash bolts 13 adapted to be projected laterally into sockets 1 1 or equivalent elements on the frame C. To actuate the bolts, bell crank levers 16 are fulcrumed in the re spective casings, and one arm of each lever has engagement with the sash bolt 18 said arm having an end slot 16 that receives a pin 15 on the sash bolt. The other arm of the bell crank lever in one casing has an end slot 16 which receives a pin 17 on a slide bar 17 In the other of said casings a block 17, constituting in eflect a separate section of the slide bar 17 is fitted, and has a pin 17 which is received in an end slot 16 in the adjacent bell crank lever 16*. The bar 17 is adapted to be moved longitudinally into the lock casing 10 of the lower sash B and projected into the lock casing of the upper sash A when the said casings are in aline ment.

The inward movement of the bar 17 presses against the bar section 17 so that the respective pins 17 17 will rock the adjacent bell crank levers and thereby project or withdraw the sash bolts 13; [In the inner position it will be obvious that the projection of the bar 17 through the casing of the lower sash and into the casing of the upper sash, will constitute said bar a coupling between the sashes and between the lock casings thereof. To hold the bar in the inner position and the bolts projected, a suitable means may be provided, such as a pivoted hook 23 mounted to be swung behind the bar 17 when the latter is in the inner position, there being a spring 22* normally tending to throw said hook into the perative position. The withdrawal of the bar 17 will, through the pin 17', rock the lever 16 of the lower sash and withdraw the sash bolt 13 thereof; to Withdraw the bolt of the upper sash from the projected positions I provide a plate spring 24: engaging Iby its free end in a notch 13 of the said olt.

The described constructions afford practical means for carrying my invention into efiect, and I would state in conclusion that I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departing from the spirit of the invention. It is to be understood that in practice, for instance, the bolt casings 11 may be set in the sashes at any desired distance from the front faces of the sashes, or close to said front faces.

Having thus described my invention, 1 claim as new, and desire to secure by Letters Patent:

1. In a sash lock, separate bolt casings separately attachable to upper and lower sashes, a bolt in each casing, a coupling bar movable longitudinally to form a connection between the two casings, and means associated with said bar and with the bolts, to project or withdraw the bolts by the longitudinal movement of said bar.
